Análise do tamanho e da forma do ôvo em galinhas das raças Rhode Island Red e Light Sussex e do híbrido entre essas duas raças
Size and shape in eggs of Rhode Island Red and Light Sussex breeds and in the hibrid Rhode x Sussex were studied. These characters are influenced by quantitative genes. Major and minor diameter were used for estimating size of the eggs and the ratio minor/major diameter for shape indice. It was found, in the material analyzed, that: a) the eggs laid by the sa- me chick are pratically uniform; b) the correlation coeficient between major and minor diameter is weak; c) Rhode Island Red has short eggs than Light Sussex; d) short eggs is dominant on long eggs; e) egg shape is the same in Rhode Island Red and Light Sussex breeds and different in the hibrid, which has rounder eggs than the breeds.
